Generative AI Consulting and Custom LLM Development
Our generative AI consulting goes past public API wrappers to design proprietary generative AI pipelines: fine-tuned foundational models, custom inference optimization, and secure data orchestration layers that produce consistent, auditable outputs.
Model weight fine-tuning and inference optimization, not prompt engineering
Most generative AI projects stall at the API wrapper stage. Pento goes deeper. As a generative AI development company, we fine-tune foundational model weights on your proprietary data, optimize inference throughput with custom serving configurations, and design secure training pipelines with strict data governance. The result is a model that behaves predictably on your specific data. When your data can't leave your infrastructure, we deploy a private LLM inside your own cloud and build the RAG pipelines that ground it in your documents.
Secure training parameters, fine-tuned weights, and custom inference stacks
Pento's generative AI approach treats model weight fine-tuning and inference optimization as the core engineering challenge. We configure secure training parameters, isolate training data in controlled environments, and build serving stacks tuned to your latency and cost targets. That work is distinct from Conversational AI architecture work. Here we modify the model itself, not the prompt layer alone, and deploy it in production environments.
How our generative AI consulting takes systems to production
Strategic assessment
We start by understanding your workflow challenges, knowledge sources, data structure, business goals, and security requirements.
The assessment pinpoints where generative AI can create the strongest impact across your organization.
Generative AI roadmap and system design
After the assessment, we create a roadmap that defines high-value use cases, system requirements, architecture recommendations, and a feasibility analysis for AI copilots or custom LLM applications.
Pilot and validation phase
Before deploying broadly, we test the system through pilots that validate accuracy, safety, retrieval quality, usability, and real-world performance.
Full implementation and scaling
Once the pilot proves out, Pento supports the full implementation of your generative AI system.
That covers infrastructure setup, API integration, model optimization, monitoring design, and training for your internal teams.
Generative AI use cases that reach production
From AI copilots to automated content systems, generative AI delivers measurable value across your organization.
AI copilots that assist employees with search, analysis, and workflow automation
Custom LLM applications tailored to industry language and proprietary data
Knowledge assistants that retrieve information instantly and improve internal efficiency
Automated content generation for product descriptions, documentation, or support
RAG systems that improve accuracy and reduce hallucination in business settings
RAG development services
Retrieval-augmented generation (RAG) grounds an LLM in your own documents at query time, retrieving relevant context from a vector database such as Qdrant before the model answers. It suits knowledge that changes often or answers that need source citations, and it reduces hallucination without retraining. When the model also needs a specific tone, format, or domain reasoning, we combine RAG with fine-tuning.
What our RAG work covers:
Private LLM deployment
When your data can't leave your infrastructure, we deploy a private LLM inside your own cloud environment. Training and inference run in isolated environments with full audit trails, and we don't train on your data with third-party providers unless that is contractually agreed. We choose between a private model and a hosted API per use case, based on accuracy, latency, privacy, and cost.
What a private LLM deployment includes:
